Red Sea Reef Foundation A (Ca-Sr) 5L – Calcium & Strontium Supplement for Corals

The Red Sea Reef Foundation A (Ca-Sr) 5L is an essential supplement designed to maintain stable calcium and strontium levels in reef aquariums, promoting healthy coral skeletal growth. Calcium is a critical seawater element, necessary for coral skeletal formation and coralline algae growth, while strontium strengthens coral skeletal structures and enhances calcium absorption.

This 5L format is perfect for large reef aquariums and long-term use, whether for manual dosing or automated dosing pumps.

Key Benefits:

✔ Enhances coral skeletal development – Provides an optimal balance of calcium and strontium.

✔ Ultra-pure formula – Free from phosphates and contaminants.

✔ Ideal for automated dosing systems – Compatible with dosing pumps.

✔ Essential for SPS and LPS corals – Supports strong skeletal structure.

✔ Cost-effective 5L format – Suitable for large aquariums and high-demand reef systems.

Technical Specifications:

• Volume: 5L

• Concentration: 1ml of solution increases calcium levels by 2 ppm per 100 liters of water.

• Composition: Calcium and Strontium in an optimal ratio.

• Recommended Use: Suitable for SPS, LPS, and soft corals.
